To all 307mm it 'mayconcern: Y

Be 1t known that I, WILLIAM CHARLES NIEBUHR, a citizen of the United States, re-

' siding at St. James, in the county of. Watonwan and State of Minnesota, have invented certain new and useful Improvements in Bundle-Conveyin Attachments for Thresh- -Machines ,an I do Ahereby declare .the fo owing to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved bundle feeding attachment for threshin machines, by the use` of which thev bundles ignom quite a lar e number of adjacent stacks may be fed to t e band cutting and feeding device of a threshing machine, without requiring the threshing'machine to be moved.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

It is a well known fact that considerable work and time are required to -change the position of a threshing machine, and to againh couple thesame up to the traction en ine use to drive the same. Furthermore, w ile the threshing machine is being moved and again connected up, a large threshinrlr crew is compelled to remain idle, and this, orf course," causes a very considerable money loss to the operator `of the threshing machine.

M invention makes it possible' to feed theV bun les from quite a large number of adjacent stacks, without requirinnr the threshing machine to be moved, and thereby reduces to a minimum the numberof movements of the threshing machine required on any particular job.

In the accompanyin drawings which illustrate the invention, li e characters indicate like parts throughout the several views.

Referrin to the drawings, Figure 1 is a view in si e elevation, showing a threshing machine ofstandard construction with my improved bundle conveying attachment applied thereto, some parts being broken away and some parts being indicated in diagram. Fig. 2 is a diagrammatic plan view of the parts shown in Fig. 1. Fi r. 3 is a detail in side 'to therear end portion of the machine case and which serves to hold the cooperating conveyer frame in an inoperative position. 4 is a plan view, wit some plarts broken away, showing in detail one of t e bundle conveying devices. Fig. 5 is a view in side elevation, but with' some parts broken away, of the parts truck which su ports the free end of the bundle conveying evice shown in detail inFigs. 4 and 5, the said parts being viewed in a direction from the outer toward the inner end of the said bundle conve ing device and shown inFig. 4. Fig. -is an elevation of the is a detail partly in e evation and partlyin vertical section, showing on v`a larger scale than in the other views the ivotal support for the inner end of the bund e conveying del vice.

Of the parts of the threshing machine, it is only desirable for the pur oses of this case to note the frame-Work l, t e cas' 2, iront wheels 3, band cutter and feeding ta le i and a transverse power-driven shaft 5, which latter, as shown, carries the usual pulley 6. The band cutting and feeding table 4 is shown as supported, at its free end, by a leg 7 of the customary construction.

Pivotally supported at each side of the machine and arranged to deliver the bundles onto the band cutter and feeder table 4, is a long conveyer frame 8. In practice these frames 8 have usually been made about thirty feet long and, at their inner ends, they have been` pivotally connected to bearing brackets 9 rigidly secured to the ends of a transverse bar 10, the latter being referably formed by a iece of metalpipe. ach ipe or bar 10 is r1 idly secured to a head 11, om whichde'pen s a tubular standard or pipe section 12.

To sup ort the tubular standard 12 with freedom or oscillatory movements on a vertical axis, it is journaled in the projecting end of a sup orting beam 13 and in the upper arm of the racket 14. On the standard 12 is a collar 15 that engages the supporting beam 13 to hold said standard against downward movements. As illustrated in the drawings, the'su porting beam 13 is bolted or otherwise rigi ly secured to another beam 13a which, in\ turn, is bolted or otherwise rigidly sccured to the machine frame 1. A

elevation, showing a brac et which is applied rod 16, the upper end of which is secured to A the casing 2, and the lower end of which is secured to the beams 13 and 13a.

The numeral 17 indicates a trussrod which connects the intermediate portion ofthe rod 16 to the machine frame, and the numeral 18 indicates the usual truss rod'whichconnects the machine frame 1 to the forwardly proj ecting portion of the casing 2.,

Journaled in and extending vertically through the tubular standard 12 is a driving shaft 19, which, at its lower end, carries a pulley 20 and, at its upper end, carries a miter gear 21. The miter gear 21 meshes with a companion gear 22 of a transverse counter-shaft 23, which counter-shaft, at its central portion, carries a sprocket 24.

To pivotally connect theinner end of the conveyer frame 8 to the brackets 9, the latter are preferably forked, as shown in Figs. 1 and 7, and said frame 8 is provided with bearing brackets 25. Said bearing brackets 25, at their projecting ends, are bifurcated to lembrace the sides of the pronged ends of the brackets 9 and are provided with rigidly secured hubs or sleeves 26 that rest loosely in the pronged ends of said brackets 9. shaft 23 just described is journaled, at its ends, in said hubs or sleeves 26.

Loosely journaled in the free end of 'the conveyer frame'8 is a transverse countershaft 27 which, at its central portion, is provided with a sprocket 28. The sprockets 24 and 28 aline with a longitudinally extended channel 29 formed between the inner edges of a air of horizontally alined skid decks 30, whiclfi latter are extended longitudinally of and rigidly secured'to the sides of said frame 8.

A. sprocket chain 31 runs over the alined sprockets 24 and 28 of the driven and idles 1 afts 23 and 27, respectively. At suitable intervals, transversely extended slats 32 are intermediatel chain 31. 'l e chain 31 and its s ats 32 constitute an endless bundle conveyer; and the said slats, when moved from the free end toward the inner end of the conveyer frame 8, slide upon and are supported by the skid decks 30. Preferably these slats 32 are formed by light metal angle strips, the pro jecting Hanges of which are cut away at the ends, as best shown in Fig. 7, so that the reduced ends, under return or idle movements, are ada ted to slide over and to be supported by uirfe strips 33 ri idly secured to and exten ing longitudina y ofthe sides of the frame 8. By the guide strips 33 the under or idle portion of the endless bundle conveyer is revented from sagging below the bottom o said frame 8. v

Rotary motion is imparted to the upright shaft 19 and, hence, through the shaft 23 to the endless bundle conveyer, by means of a driving belt 34 that runs over the pulley i porting bars 13a.

The

secured to the s rocket as shown, in suitable bearings on the sup- The counter-shaft 36, 1n turn, is driven by a sprocket chain-37 that runs over sprockets 38 and 39, (indicated by dotted lines in Fig.` 1) respectively, on the shafts -5 and 36. The shaft 5 is driven in the usual way by a belt (not shown) but which runs over the ulley 6 thereof.

From the above it 1s evident that the AconveIyer frames 8 are mounted both for verti-v ca and for lateral pivotal movements, and that motion will be imparted 'to the endless conveyer 31-32 throu h the miter gears21 and 22, re ardless of t e positions assumed by the sai frames.

The outer end of each conveyer frame 8 is adjustably supported by'means of a so-called truck, preferably constructed as follows: A pair of truck wheels 40, located one ahead of the other, are journaled on crank-like trunnions 4'1 which, in turn, are pivotally connected to the lower ends of upright posts 42.. These posts 42, near their lower ends, are rigidly tied together by upper and lower tie bars 43 and 43a and truss bars 44 (see Fig. 6). The trunnions 41 are provided with extended arms 45, the free ends of which are adjustably connected, by links 46, (see Figs. 1 and 6) to a erforated flange of the lower tie bar 43. gy' securing 'the links 46 in different erforations of the said bar 43 the two wheels 40 may be set to travel in different curves.

Mounted to slide vertically on each post 42 is a small truss frame 47 that projects forward and rearward of the coperating ost. The forwardly projecting ends of the ames 47 are connected, by asmall shaft or rod'48, and the rearwardly projecting ends thereof are likewise connected, by a shaft or rod 49. Loosely journaled on the rods 48 and 49 are flanged wheels 50 upon which the depending side boards of the cooperating conveyer frame 8'rest loosely.

Simultaneous upward and downward movements are adapted to be imparted to the two supporting frames 47 by a windlass comprisinga windlass shaft 51 and a pair of cables 52. The shaft 51 is journaled in suitable bearings on the posts 42 and is provided, at one end, with an operating crank- 53 and a ratchet wheel 54. A lock dog 55, pivoted' to the adjacent post 42, .cooperates with the ratchet wheel 54 to lock the shaft 51 in any desired position. guide sheaves 56 on the upper ends of the posts 42 and their down-turned ends are attached one to each ofthe lifting frames A47.

Mounted on each side of the rear end of the case 2 for lateral swinging movements,'is a so-called latch bracket 57, upon which the free end'of the corresponding conveyer 8 is The cables 52 lrun over .'into lan, inoperative position, shown by A other end of the conveyer frame may be scarsa adapted to be `rested and held when turned dotted lines ,1n Fig. 2. The two conveyer frames A8 are turnedinto the positions indicated by dotted lines in Fig. 2 when themachine is to be moved from'one job to another, or when, for other reasons, the machine is to be'moved over the'road.' When the conveyerframes are turned outward into operative ositions, the latch frames 57 may be turnedJ against the side of the machine case and entirely out of the way. f

When the machine has been pro erly set and connected in the vicinity o t several stacks of grain, the conveyer frames 8 may be'moved pivotally in a horizontal direction from one stack to the other, and its free end may be raised or lowered to any desired altitude, so that it Will be in position to receive in the most advantageous manner the bundles of any articular stack.- As the stack is lowered ib from, the inner end of the conveyer frame should, -of course, also be lowered. After one' stack has been fed to the machine lthe uickly moved into position'to receive bunles from an adja ent stack. The twowheeledtruck makesI lateral swinging movements of the conveyer frame a ver easy matter, and the Windlass applied to t e said truck makes it an easy matter to quickly raise or lower the free end of the conveyer frame. As shown, the posts 42 are provided with vertically spaced perforations 59,

through which pins may be inserted tov support'tthe Jramesr 47 and, hence, the free end of the conveyer frame, in dierent vertical ositions independently of the windlass. L ometimes it is desirable to support the conveyer frame 8 at its extreme outer end, and at other times it is .desirable to support the same at its intermediate portion, or a considerable distance from its free end. This is easily done by moving the supporting truck laterally so as to cause the wheels to travel under the sides of said conveyer frame.

As is evident, all of the bundles delivered onto the conveyer frames 8 will, by the endless conveyers 31-32, be deposited upon the band cutter and feeder table 4, from whence they will be carried to the threshing cylinder, ypreferably by the customary devices.

In Fig. 2 I have shown a curved deflecting. plate ap lied to one sideof the delivery end of eac conveyer frame 8. These deflecting plates 60, when thev conveyer frames are turned transversely of the threshing machine, serve to turn the bundles so that they will be delivered onto the receiving table 4, extending in a direction a proximately parallel to the longitudinal irection of the` threshing machine. These plates 60 should be detachably secured by y the carrying of bundles there-- for vertica rection of the machine.

`The bundle conveying device constructed substantially as illustrated in the drawings has been ut into actual use in connection with a t reshing machine and has been found highly efficient for the purposes had in view. B the use thereof great'economy in labar an hence, in the cost of threshing of. grain, has been accomplished. i
